Handy white cardboard postal mailing boxes with tuck-in locking flap lids.

Postal boxes arrive flat but ready for assembly. No packing tape is required for assembly but taping your postal boxes before mailing gives added security.

Postal box dimensions are displayed as:
Length x Width x Height

Postal box dimensions are displayed in millimetres (mm) and inches (").

We always express the internal dimensions of our boxes to enable you to accurately calculate whether your item(s) will fit.

You might be interested in our Brown Vari-Depth Cardboard Boxes, these are lightly pre-scored at certain heights enabling users to trim down the corners of the box and fold down the sides to create a cardboard box with a reduced depth.
